Functionalized polystyrene latex particles were obtained either by seed particle functionalization or by the shot‐growth procedure using 2,2′‐azobis (2‐amidino‐propane) dihydrochloride as an initiator and vinylbenzylamine hydrochloride as a cationic monomer. The capabilities of both processes to produce functionalized particles in terms of functionalization yields coming from surface amino group titrations were compared. Different titration methods were performed and a new technique was introduced using fluorescamine.
